Abstract: A climate control system includes a memory, a compensation module, and a climate control module. The memory is configured to store images captured by one or more image sensors. The compensation module is configured to: based on the images, estimate a clothing level of a first occupant in an interior cabin of a vehicle or receive the clothing level from at least one of an edge computing device or a cloud-based network device; determine a first EHT setpoint; and determine a first resultant EHT based on the clothing level and the first EHT setpoint. The climate control module is configured to: determine a first EHT error based on the first resultant EHT and a cabin temperature setpoint; determine a control value based on the first EHT error; and set climate control parameters to control a temperature of a first zone within the interior cabin based on the control value.

The method may include receiving a signed distance function (SDF) data file that represents the design geometry of the vehicle body. The method includes receiving a range of inflow boundary conditions. The processor processes the SDF over the range of boundary conditions, using the CNN, to generate therefrom drag and lift outputs for the design geometry. The drag and lift outputs may be displayed in the form of one or more intensity maps.

Abstract: A vehicle a sensor system disposed adjacent to a headrest portion of a seat within a passenger compartment of the vehicle. The sensor system includes at least one of an air velocity sensor, an air temperature sensor, a radiant heat flux sensor, a heat flux sensor, or a humidity sensor. The sensor system is positioned near the headrest, facing a forward end of the vehicle, in a position that is not blocked by a head of a passenger seated in the seat. The sensor system provides data related to the air velocity, the air temperature, the radiant heat flux, the heat flux, or the relative humidity, enabling a climate controller to accurately calculate a current Equivalent Homogenous Temperature (EHT) of a passenger seated in the seat. The climate controller may then control a climate system of the vehicle based on the calculated EHT to provide a desired EHT.

Abstract: A method of regulating thermal comfort of an occupant of a vehicle cabin uses a radiant heating tile powered via an energy storage device to generate thermal energy. The method also includes detecting the occupant's position via a position sensor and detecting the occupant's surface temperature and detecting a temperature of the tile via at least one temperature sensor. The method additionally includes determining, via an electronic controller, a rate of change of occupant's surface temperature and a difference between the tile temperature and the occupant's surface temperature relative to a predetermined temperature set-point. The method further includes regulating, via the electronic controller, a power input from the energy storage device to the tile in response to the determined rate of change of the surface temperature and the determined difference between the tile temperature and the occupant's surface temperature to thereby regulate the occupant's surface temperature.

Abstract: An adaptive radiant heating system regulates a climate inside a motor vehicle cabin having a seat for a vehicle occupant. The system includes radiant heating tiles arranged proximate the seat and powered by an energy storage device. The system also includes a first sensor for detecting a position of the occupant and generating a first signal indicative thereof. The system additionally includes a second sensor for detecting a temperature within the cabin and generating a second signal indicative thereof. The system furthermore includes an electronic controller in operative communication with the tiles and the first and second sensors, and configured to regulate the climate proximate the seat via selective control of the tiles. The controller is configured to receive the first and second signals and activate at least one of the tiles in response to the first and second signals, to thereby regulate the climate proximate the seat.

The solar load prediction module is configured, based on the map information and the environment information, to (i) determine a route of a host vehicle, (ii) predict solar loading on the host vehicle along the route, and (iii) predict an amount of energy to be consumed by the host vehicle over the route based on the predicted solar loading. The eco-routing module is configured, based on the amount of energy to be consumed by the host vehicle over the route, to at least one of (i) determine whether to follow the route, or (ii) inform a user of the route and the predicted amount of energy to be consumed over the route.
